solve the following simultaneous equation
4x-3y=1
x-2y=4

Answer:

Whether her conversion is correct or not, you can just base it on the true answer. For this problem, we apply the technique of dimensional analysis. You can like units if they both appear on the numerator and the denominator side. The solution is as follows:

Mass in ounces = 3 kg * (1,000 g/ 1 kg) * (1 ounce/28.35 g) = 105.82 ounces

Answer:

8.94 m

Step-by-step explanation:

Use the Pythagorean Theorum - [tex]a^2 + b^2 = c^2[/tex]. Use leg 1 as a, leg 2 as b, and the third side as c.

We know leg 1 is 4, and that leg 2 is twice as long as leg 1...

[tex](4)^2 + (4*2)^2 = c^2[/tex]

Now, we use the Order of Operations to find [tex]c^2[/tex]...

[tex]4^2+8^2=c^2\\16+64=c^2\\80=c^2[/tex]

Now, we find the square root of [tex]c^2[/tex] to find c...

[tex]\sqrt{80} =8.94[/tex]

So, the length of the third side is 8.94 m.

Answer:

Volume is equal to

L×W×H

=(10×9×7)cm

=90×7

=630

The volume of the prism is 980cm3.

We are given that;

The dimensions= 4*7*9*2*10cm

Now,

A rectangular prism is a three-dimensional shape that has two at the top and bottom and four are lateral faces.

The volume of a rectangular prism=Length X Width X Height

Volume of upper prism;

=5*4*40

=800cm3

Volume of lower prism;

=2*9*10

=180cm3

Total volume= upper volume + lower volume

=980cm3

Therefore, by the rectangular prism the answer will be 980cm3.

Answer:

reflection over Y axis

Step-by-step explanation:

Answer:

I believe it is D) a reflection over the Y-axis

Step-by-step explanation

it is going over the Y-axis as if it is a sort of mirror, if it were going over the x-axis it would be flipped upside down, if it was A the shape would be going over the original shape. I don't know how to explain C. (I hope this helped and I hope it was correct lol)

Answer:

Angle k measures 60 degrees!!!

Given:

The polygon in the given figure are similar.

To find:

The missing side length.​

Solution:

We know that the corresponding sides of similar figures are proportional.

The given polygons are similar, so the their corresponding sides are proportional.

[tex]\dfrac{x}{15}=\dfrac{32}{40}=\dfrac{32}{40}[/tex]

So, the missing values in the equation of proportion are 15, 40, 32 respectively.

On solving the above equation, we get

[tex]\dfrac{x}{15}=\dfrac{4}{5}=\dfrac{4}{5}[/tex]

[tex]\dfrac{x}{15}=\dfrac{4}{5}[/tex]

[tex]x=\dfrac{4}{5}\times 15[/tex]

[tex]x=12[/tex]

Therefore, the value of x is 12.

Answer:

x=-1  y = 1/3

x = 1  y = 3

x = 3  y = 27

Step-by-step explanation:

y = 3^x

Let x = -1

y = 3^-1 = 1/3^1 = 1/3

Let x = 1

y = 3^1 = 3

Let x = 3

y = 3^3 = 27

2x + y = -4

slope = -2

perpendicular slope = 1/2

new equation = x - 2y = x

(1) (2)= 2

(-2) (-8)=16

2+16 =18

new equation = x - 2y = 18

Answer:

y = [tex]\sqrt{16}[/tex] x

that is equal to  y = 4x

[tex]\sqrt{16}[/tex] = 4

when graphing (x,y) the x is the horizontal value of the point (east west)

and the y in the vertical (north south) ....

if you have y = x it would be a 45 degree line that goes from the lower left to the upper right....

if you compare the red line  the point  1,1  (y=x) versus 1,4 (y=4x) in the blue line you will see that it is "stretched" upward

Answer:

f(x) = 1/2x + 6

Step-by-step explanation:

So before we even look at the first given formula, let's use the second formula: f(x) = -5.

Plug this formula into the x:

0 <= -5 <= 7

Is this true? Is -5 greater than or equal to 0 and less than or equal to 7?

No, this is false.

So the formula, f(x) = -5, is not the graph of f.

That only leaves one possible option!

Answer:

Plot 3 points

Step-by-step explanation:

Let plot the vertex

[tex] - \frac{b}{2a} [/tex]

[tex] - \frac{ - 2}{2} = 1[/tex]

Plug this value in

[tex]y = {1}^{2} - 2 = - 1[/tex]

So our minimum point is at (1,-1).

This also means our line of symmetry occurs about x=1.

Let use some point like 0.

[tex]0 = {0}^{2} - 0[/tex]

So this means point (0,0) is a point. Since 1 is the line of symmetry, (2,0) is a point.

=======================================================

Explanation:

Extend segment MN such that it intersects side ST. Mark the intersection as point A. See the diagram below.

We're given that angle MNT is 72 degrees. The angle TNA is equal to 180-(angle MNT) = 180 - 72 = 108 degrees, since angles MNT and TNA add to 180.

For now, focus entirely on triangle TNA. We see from the diagram that T = 34 and we just found that N = 108. Let's find angle A

A+N+T = 180

A+108+34 = 180

A+142 = 180

A = 180-142

A = 38

So angle NAT is 38 degrees.

----------------------------

Since segment MA is an extension of MN, and because MN || SQ, this means MA is also parallel to SQ.

We found at the conclusion of the last section that angle NAT was 38 degrees. Angles QST and NAT are corresponding angles. They are congruent since MA || SQ. This makes angle QST to also be 38 degrees

----------------------------

The angles QSR and QST are a linear pair, so they are supplementary

(angle QSR) + (angle QST) = 180

angle QSR = 180 - (angle QST)

angle QSR = 180 - 38

angle QSR = 142 degrees

Answer:

3.2 liters

Step-by-step explanation:

The first thing we want to do is find the amount of water it leaks hourly

To do so we divide the amount of water it leaks in 3 hours ( .48 ) by 3

.48/3 = .16

So the faucet leaks .16 liters per hour

Now to find how much water the faucet leaks in 20 hours

To do this we simply multiply 20 by the hourly leakage amount (.16)

.16 * 20 = 3.2

So in 20 hours the faucet would have leaked 3.2 liters of water

Answer:

3.2 liters of water :)!

Step-by-step explanation:

If 0.48 every 3 hours we can do 0.48/3 to find the amount it loses every hour.

0.48/3=0.16

Then if we multiply 0.16 by 20 we will get the amount it loses in 20.

0.16x20=3.2

Hence, it loses 3.2 liters of water every 20 hours.

Hope this helps:)!

Answer:

according to my equation it is 61.6

Answer:

y + 2.3 = 0.45x

y = 0.45x - 2.3

-2y = 4.2x - 7.8

-2(0.45x - 2.3) = 4.2x - 7.8

-0.90x + 4.6 = 4.2x - 7.8

-0.90x - 4.2x = -7.8 - 4.6

-5.1x = - 12.4

x = -12.4 / -5.1

x = 2.4

y + 2.3 = 0.45x

y = 0.45(2.4) - 2.3

y = 1.08 - 2.3

y = -1.2

solution is : (2.4, - 1.2)

Step-by-step explanation:

In the month of September there are only 30 days. So assuming Sohanlal works the entire month of September we will multiply how much he makes daily which is 160 times the amount of days he works which is 30. this will look like this:

160 × 30 = 4800

Answer:

26 degrees

Step-by-step explanation:

[tex] \frac{ \sqrt{19} }{ \sin(x) } = \frac{10}{ \sin(90) } [/tex]

[tex] \frac{ \sin(x) }{19} = \frac{1}{10} [/tex]

[tex] \sin(x) = \frac{\sqrt{19} }{10} [/tex]

Take the sin inverse

we get 26 degrees
